ABSTRACT

Aims

To study the effects of routine HLA screening and the policy of avoiding donor-dominant one-way HLA match to prevent graft-versus-host disease (GVHD) after living donor liver transplantation (LDLT).

Patients and Methods

The records of potential living liver donors and recipients who attended our center between 2007 and 2018 were reviewed retrospectively.

Results

Of the 149 patients who underwent LDLT and survived longer than 3 months, two developed GVHD despite our strict policy. The first patient presented with grade II GVHD limited to the skin. She was treated successfully by briefly discontinuing immunosuppression and switching to everolimus. In the second case, the policy had been relaxed due to the availability of a single donor for ABO-incompatible transplantation without any intervention to decrease anti-A antibody levels (special case: A2 to O). Nevertheless, the patient presented with grade I GVHD limited to skin and was treated successfully by adding oral methylprednisolone to tacrolimus and mycophenolate mofetil. To the best of our information, this is the second reported case who recovered from GVHD after LDLT from a donor, homozygous at HLA A, B and DR and a recipient, heterozygous for all. Sixteen potential donors (1.2% of all candidates) of 14 recipients were disqualified solely on the basis of the HLA results; five of these patients died due to unavailability of another donor.

Conclusion

The results support the policy of avoiding HLA combinations that preclude immune recognition of graft lymphocytes as foreign to decrease the risk of GVHD after LDLT.

Conflicts of Interest
